Ian Boston commented on DS-1396:
--------------------------------
Using rngd wiring bits from /dev/urandom to /dev/random produces bits at a rate
of 9700 Kbit/s which and passes a FIPS-140 test (rngtest), however it doesn't
make the startup much quicker, so this might not be related to /dev/random, but
find / still unblocks the startup.
Output from rngtest with rngd running.
~# cat /dev/random | rngtest -t 5
rngtest 2-unofficial-mt.12

> I am experiencing extremely slow startup times for DS3-rc3 on Linux with the
> stock sun JVM, and I have experienced total hangs 11:19-15:09 of the JVM with
> perfect operation after the end of the period (no restart of any form was
> required). By slow startup I mean just bringing up solr, xmlui and jspui can
> take 60 minutes.
> I think this is due to /dev/ramdom on the OS not getting sufficient entropy,
> probably caused by the Bouncy Castle crypto APIs or the new SecureRandom() in
> Eperson.
> performing a
> find /
> as root appears to unstick the JVM on startup, pointing to an entropy issue
> (find / will cause disk I/O not from cache generating low level device driver
> entropy)
> Has anyone else seen these issues ?
> Is there a known fix (other than performing a find)
> I have already tried -Djava.security.egd=file:/dev/./urandom
